Question 220954: hi, i need help in solving an equation using the quadratic formula,
i know what the quadratic formula is but i don't know how to apply it to this particular question
the question is: 2x^2+7x = 1-2x^2
the fact that it isn't in the form x^2 + bx + c = 0 is making it hard for me solve,
at the moment i've got as far as changing the equation to 2x^2+7x - 1-2x^2=0
but i don't know whether thats right or wrong :S
thank you!

the question is: 2x^2 + 7x = 1 - 2x^2
:
Group like terms on the left
2x^2 + 2x^2 + 7x - 1 = 0
:
Combine the like terms
4x^2 + 7x - 1 = 0
:
Now it is in the familiar ax^2 + bx + c form that we all recognize and love.
where a = 4; b = 7; c = -1
:
Hopefully you can take it from here, if not let me know. ankor@att.net
